libarena is a custom memory allocator interface and implementation. Four
allocators are provided: flat LIFO arena allocator, object pool allocator
and two malloc(3) wrappers: one which returns the pointers unadulterated
and one which obeys the requested, arbitrary alignment. These can be used
directly, or through their exported prototype interfaces.
libarena is meant to provide a baseline interface so allocators can be
stacked, and to provide a simple and well defined interface for libraries
and applications without becoming mired in features or capabilities. It is
not meant to restrict or confine what custom allocators can actually
accomplish. For instance, the included pool and arena allocators include a
suite of string utilities which aren't available in the generic exportable
interface. Note that these string utilities are built upon a generic
interface (see util.h) which can take the prototypical allocation context,
so they are also available to any 3rd party compatible allocators.
